Good to know
Before you use it
- These are ZIP Code Tabulation Areas, the Census Bureau's map of residential ZIP codes. ZIP codes used only for PO boxes or a single organization (20500 is the White House) have no area, so they aren't included.
- City is the city or community holding most of the ZIP's residents. For 4,993 rural ZIP codes outside every community it is the nearest one, and InCity is false. It usually matches the city on mail, but not always.
- County is the one holding most of the ZIP's residents. In Connecticut it is the planning region, which replaced counties in 2022.
- CityGEOID matches GEOID in the U.S. cities collection, and CountyFIPS matches other Census data.
- In every format, dates are written as yyyy-MM-dd, and yes/no values as true or false. An empty value means nothing was recorded.
